Answer:
of the distance
Step-by-step explanation:
We know that a ferry traveled of the distance between two ports in
hours.
In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :
The rate of the ferry is the same at any time.
The ferry will travel of the distance in
hours.
If we divide each fraction by 3 ⇒
and
We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :
The ferry will travel of the distance in
hours.
Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒
and
We found out that the ferry will travel of the distance in 1 hour.
Answer:
Step-by-step explanation:
We have been given an equation . We are asked to find the solutions of our given equation.
First of all, we will cross multiply our given equation as:
Subtract from both sides:
Now we will factor out .
Now we will factor by splitting the middle term.
Now we will use zero product property and solve for x as:
Now, we will check for extraneous solutions.
We can see that will make both denominators zero because our function is not defined at
.
Therefore, the solution for our given equation is .
<u>ANSWER: </u>
Jack picked 10 ears of corn. The amount of corn left is ears of initial corn.
<u>SOLUTION: </u>
Given, Jack picked 10 ears of corn.
Now the total corn present is 10 ears.
He and two of his sisters ate two each.
Then, remaining corn = 10 ears – eaten corn
= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)
= 10 – 6 = 4
Now, the amount of corn left in fraction is remaining corn divided by initial corn.
Left over corn =
Hence, the amount of corn left is ears of initial corn.
